To c aZL'wz-om it may concern Be it known that l, FRANK A.. VATH, a rciti'en of the United States, residing in Chicago, in the county of Cook and State of illinois, have invented certain new and useful improvements in Cooking Apparal tus, of which the following is a specification. Thisinvention relates to improvements in I cooking apparatus ofthe electric type, and

oneof thejobjects isto simplify-the same, and to `pian/'ide an improved, simple, durable, light and portableI device of this charaeter, which will beedective and efficient iu operation, and onefin whichy the ordinary radiator vacuum heating element or lamps may be employed as the source of heat.

A Afurther object is to provide an improved, simple andeiiiective device of this Yclassin which the radiator elements maybe controlled at will-4 to regulate the amount of heat, and in which apparatus, afterthe ar ticles have started to cook, the source of heat may be cut oilA and the apparatus will then operate as afirele'ss or heat retaining cooker;

To the attainment of'these ends, and the accomplishment of other new and useful objects as will appear the invention consists in the features of novelty iu'sub'stantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompany'iug drawings in which,

lteferringniore particularly to the draW-' ings and in the present exempliiication of this invention', the apparatus consists of a casinghaving a base 10 constructed of any desired or suitable material, side and back walls 11,12 and atop 18. The casing is also of the venting device.

of the cirprovided with a front wall designated gen-vv erally by the reierencenumeral 14 and the side,.bacl and' front walls, as well as the top arezpieferarbly.constructed of sheet material. fallire sides and back walls are preferably of partly in section andf a single-piece-bent into thedesired shape and the front wall 14 is connected with the sido Walls in any desired or suitable man ner, such as b ynieans ofllanges `15 and fastoning devices 1 6, passing through a porn tion ofthe side walls and the respective flanges. The top 13 issecured to the -front wall, preferably b means of a flange 17 and fastening devices 8 fastenedithrough a portionof the top and the flange while the rear edge of the top is preferably lang'edover the upper edge of the bja-cl; as at 19, and se the closures 22 which are provided preferinafter described. Arranged within vthis outer casing and spaced from the walls,

cured by fastening devices 20. The frame thus f ormedconstitutes the outer casing of the apparatusand the front wall is Yprovided v with ,door openings 21 closed by means ot thereof is another casing comprising side l walls 23, back wall 24 and top wall 25. This inner casing rests upon the bottom 10 of the outer casing and which bottom also forms the bottom of the .inner casing. The inner casing is of a size somewhat less than the size of the outer casing to form a ,space therel'uetween, and within which space is arranged heat insulating material 26, the space being preferably only partially filled so as vto leave a dead air space 27 between the in sulating material and the outer casing.l The inner easing thus formed is divided into two compartments by means of spaced parti-v tions 28 which latter are secured to the top and bottom walls thereof, and also'to the back wall 24 by means of flanges 29 and fastening devices 30, the back wall 24 and the slots 31, 32, registering with the space vbef tween the partitions 28 vto permit the insu-' lating material 2G to be placed between the partitions.

A substantially U-s'haped memn ber is securedby means of fastening. devices 33 to the front wall 14 of the outer casing as shown more clearly `in Fig. y-3 and this element 32 may also 'bel provided -with a slot 34 through which the insulating ma-4 terial'26 may be inserted into the spacev be,- tween the element and the front 14. The partitions 28 are secured to this element 32.a by means of flanges 35 and fastening devices 36. In assembling this portion of the mechanism, the elements 23, 24, 28, 32a, and 14 A,ni-aybe secured :together and then the insulating 'material 2 6 applied E tlieneto,

los

which material is preferably in plastic form. The outer casing may then be secured in position. The structure `thus formed embodies two compartments 37, 38 which are insulated `from each other,y and one ot" the door openings 21 is provided for each compartment. v

The source of heat in the present inven tion embodies vacunn heating elements or radiator lamps 89 of the ordinary and well known construction, and it is one ot' the objects of the present invention toprovide a device of this character in which these heating elements may be utilized as the source of heat and to provide a means whereby any inexperienced person may readily remove one or more of the elements and replace them as the necessity requires. These heating elements 3S) project through suitable openings in the bottoms of the respective compartments 3T, 38, and arev preferably arranged close to the dividing partition between the compartments. The openings through which the elements extend, are ot' asize slightly larger than the elements, so aste form an air space therearound for admitting outside air into the compartments,toy -ventilate the latter. The extremities of the elements pro, ject through theeopenings and engage any suitable sockets l() which latter are supported by brackets il which in turn are supportfed by a frame i2 'having legs a8, and upon which frame. the casing rests. The frame is preferably of such a` size that the lower portions o't the side, back and iront walls of the casing will overhang the trame, as shown more clearly in Figs. 2 and et, and thereby hold the parts against accidental displace-` ment, but permitting the casing to be removed trom the Vtrame when desired.

rlfhe elements 39 are placed in position from the inside of the respective comparti ments and in order to protect the elements against injuryY l'rom articles beingV placed in the compartments, a removable partition il preferably oi' a rcticulated structure is provided in each compartment. These partitions are removably held in position by means of suitable. guide Way/s45, so arranged that when the closures are opened, the partitions may be readily removed through the openings 21 to permit access to l the elements.

In' order to reduce the space which is t0 be heated adjacent the elements, the parti tions 28 may be dellected as at 4G, to any extent, and the elements 39 may be arranged close to each other. The source ot' electric energy is supplied to the elements through the comluctors 47, 4S, connected to a suitable socket 49 into which socket a plug` 50 is adapted tobe inserted apd which plug electrically connected -with the line wires 51, The elements 39 inv each compartment are connected in multiple and a three point switch 53 is provided for each of the circuits. This switch is of the ordinary and well known type and is arranged at a convenient position at the front of the apparatus to be manipulated by the. operator and thereby cut out or in in any one or more of the elements for controlling the 4temperature, as is Well understood..

Arranged within each compartment are supports 54 preferably carried by one4 of the Walls ofthe compartment and the respective partitions 44, and" lheat retaining elements or plates are adapted to be held in position by these supports. j

A vent tube 56 is provided foreach of the compartments and leads preferably from -a point adjacent the top thereof. This tube extends ,from the inside ol. .the compartment through the Wall of e casingto the outside thereof, andis provided with sets ot' holes 5T, 58, 59, the .latter being. controlled by a cap (30 having a slot 6l, therein, the cap being so arranged that by rtatingit upon the end of the tube 56, either` one of the sets 4 of apertures 57,k 5S, 59, will bev brought into communication with the slot (51 for regulating the escape of vapors. This tube 56. eX`- tends through a sleeve tbetiveenthe Walls of the inner `and outer casing as shoivn more clearly in Fig. 5 and the tube Is held in position b v means ot' a nut or collar G3 on the inside ot' the compartment and a similar nut or collar (il on the outside ot' the casing, the sleeve (32 serving as a brace or 'support' for the walls oi the casing to prevent injury hen the collars G3 and (il are being adjusted.

The closures 29 are providedwvith transparent panels (351 any number of which may be employed, but three are shown herein. These panels (35 are secured in a frame 66 which is adapted to be inserted into an opening in the closure, as seen more clearly in Fig. 3. The trame (5(3 is provided with a flange GT which rests against the outer face ot the closure `and the frame andpanels may be held against accidental displacementin any suitable manner such as by means of a plate` 68 arrangetil adjacent the inner face of the closure and vabutting the inner end of the frame (36 and which plate' is secured to the frame and closui A'fastening devices (39.15

` Vv'itlrthis in'iproved construction it will ber manifest that a very lightl structurefis .provided and by the provision of the vapor outlet 56', and the elements 55, two di'erent- ,cooking operations mayY be performed simultaneously within the same compartment. This is accomplished by arranging the elcineiits 55. shown in the right hand coxnpartnient in Fig. 2. in the manne; as shown and by placing the article to be baked upon the lower element, and the article tobe boiled upon the`upp'er element. The current is ,'e by means of suitableA character described, embodying a 'ing for controlling' the lamp,

partment for meer.,

then turned ont Vand afte'r the required amount o'f'heat is supplied to the compart! ment, andthe articles begin tolcool, the current may- 'be their shut and the cock` ing' will then' ,proceed iii the'sa'me manner as in the'l ordinary tireless cdoker. 'The vapor' arisingtroin the articles'in `the rupper prtion of Ithe. compartment will pass out of the tubulafmember 56 and will not come into contact with the articles in the lower portion of the c"oinpartment.`

Ubyiously-v the current may be allowed to remain 4on Iduring the cooking operation, it desired l l lt will further be mganifest that 'withytliisi' improved construction any inexperienced. person'may readily remove or insert theeleig ments 39,' the latter being protected by the partition; 4:41,' and it is also possible to utilize the ordinary vandwell known vacuum heat"- ing element o'r radiator'lamp which 'are' well known and'caia bje'readily obtained, 'and ,the apparz'itus repaired in this respect without necessitating the'fservices ora "skilledmechanic.` Fi'irthermor'e'by arranging the heat# ing elementsv at'the side of the compartment so that'they will be above'the bottom ther'ely of, they l'willbe out' 'of the way and in a pbsi` tion in which foreign'particles or substances will not drop thereon, and' will also permit` the bottom of the' compartment to be readily cleaned with'outremoring or'disturbing the i elements." l
